What is the IQ of a nonverbal autistic person? The answer isn’t one-size-fits-all. IQ scores for nonverbal autistic individuals vary widely, and standard tests often underestimate their abilities.

What Is the IQ of a Nonverbal Autistic Person? Key Data

• Average Scores: Studies show the mean nonverbal IQ for autistic children is about 73.5, while verbal IQ averages around 65.5. Full-scale IQ for autistic individuals often ranges from 68 to 70.
  
  
  

• Testing Challenges: Standard IQ tests may not capture the true strengths of nonverbal autistic people. Many score higher on nonverbal or visual reasoning tasks than on verbal tests.
  
  
  

• Hidden Abilities: Research finds that nonverbal autistic individuals can show average or even above-average intelligence on tests that focus on pattern recognition and abstract thinking.
